Hocomonco Pond
Hocomonco Pond is a recreational pond located in Westborough, Massachusetts near Route 9. Also called Hobomoc Pond, it was named for Hobomok, a Wamesit Indian evil spirit. The pond and adjacent land are a Superfund site. Superfund site A wood treatment and preservation plant operated on a site near the pond during the 1930s and 1940s. The business saturated wood products (e.g. telephone poles, railroad ties, pilings and fence posts) with creosote to preserve them. During the treatment process, excess creosote and wastes where discharged to an unlined pit, the "former lagoon". The creosote, which contains carcinogenic polyaromatic hydrocarbon (PAH) compounds, seeped into sediments, soil and groundwater. A storm drain built in the 1970s along the east side of the former lagoon transported liquid contaminants to the pond. The site was added to the National Priorities List The National Priorities List (NPL) is the priority list of hazardous waste sites in the United States eligi ...

Westborough, Massachusetts
Westborough is a town in Worcester County, Massachusetts, United States. The population was 21,567 at the 2020 Census, in over 7,000 households. Incorporated in 1717, the town is governed under the New England open town meeting system, headed by a five-member elected Board of Selectmen whose duties include licensing, appointing various administrative positions, and calling a town meeting of citizens annually or whenever the need arises. History Before recorded time, the area now known as Westborough was a well-travelled crossroads. As early as 7,000 BCE, prehistoric people in dugout canoes followed the Sudbury and Assabet Rivers to their headwaters in search of quartzite for tools and weapons. From 1200 to 1600 CE, seasonal migrations brought Nipmuc Indians to hunt and fish near Cedar Swamp and Lake Hoccomocco. Using Fay Mountain as a landmark, Indians crisscrossed Westborough on well-worn paths: the old Connecticut Path leading west from Massachusetts Bay; the Narraganse ...

Massachusetts Route 9
Route 9 is a major east–west state highway in Massachusetts. Along with U.S. Route 20 (US 20), Route 2, and Interstate 90, Route 9 is one of the major east–west routes of Massachusetts. The western terminus is near the center of the city of Pittsfield. After winding through the small towns along the passes of the Berkshire Mountains, it crosses the college towns of the Pioneer Valley and then south of the Quabbin Reservoir and the rural areas of western Worcester County. Entering the city of Worcester from the southwest corner of the city, it passes through the center of the city and forms the major commercial thoroughfare through the MetroWest suburbs of Boston, parallel to the Massachusetts Turnpike. Crossing the Route 128 freeway circling Boston, it passes through the inner suburbs of Newton and Brookline along Boylston Street, and enters Boston on Huntington Avenue, before reaching its eastern terminus at Copley Square.

Superfund
Superfund is a United States federal environmental remediation program established by the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA). The program is administered by the United States Environmental Protection Agency, Environmental Protection Agency (EPA). The program is designed to investigate and clean up sites contaminated with hazardous substances. Sites managed under this program are referred to as "Superfund" sites. There are 40,000 federal Superfund sites across the country, and approximately 1,300 of those sites have been listed on the National Priorities List (NPL). Sites on the NPL are considered the most highly contaminated and undergo longer-term remedial investigation and remedial action (cleanups). The EPA seeks to identify parties responsible for hazardous substances released to the environment (polluters) and either compel them to clean up the sites, or it may undertake the cleanup on its own using the Superfund (a trust ...

Creosote
Creosote is a category of carbonaceous chemicals formed by the distillation of various tars and pyrolysis of plant-derived material, such as wood or fossil fuel. They are typically used as preservatives or antiseptics. Some creosote types were used historically as a treatment for components of seagoing and outdoor wood structures to prevent rot (e.g., bridgework and railroad ties, see image). Samples may be found commonly inside chimney flues, where the coal or wood burns under variable conditions, producing soot and tarry smoke. Creosotes are the principal chemicals responsible for the stability, scent, and flavor characteristic of smoked meat; the name is derived . The two main kinds recognized in industry are coal-tar creosote and wood-tar creosote. The coal-tar variety, having stronger and more toxic properties, has chiefly been used as a preservative for wood; coal-tar creosote was also formerly used as an escharotic, to burn malignant skin tissue, and in dentistry, to pre ...

Carcinogen
A carcinogen is any substance, radionuclide, or radiation that promotes carcinogenesis (the formation of cancer). This may be due to the ability to damage the genome or to the disruption of cellular metabolic processes. Several radioactive substances are considered carcinogens, but their carcinogenic activity is attributed to the radiation, for example gamma rays and alpha particles, which they emit. Common examples of non-radioactive carcinogens are inhaled asbestos, certain dioxins, and tobacco smoke. Although the public generally associates carcinogenicity with synthetic chemicals, it is equally likely to arise from both natural and synthetic substances. Carcinogens are not necessarily immediately toxic; thus, their effect can be insidious. Carcinogens, as mentioned, are agents in the environment capable of contributing to cancer growth. Carcinogens can be categorized into two different types: activation-dependent and activation-independent, and each nature impacts their level ...

Polycyclic Aromatic Hydrocarbon
A polycyclic aromatic hydrocarbon (PAH) is a class of organic compounds that is composed of multiple aromatic rings. The simplest representative is naphthalene, having two aromatic rings and the three-ring compounds anthracene and phenanthrene. PAHs are uncharged, non-polar and planar. Many are colorless. Many of them are found in coal and in oil deposits, and are also produced by the combustion of organic matter—for example, in engines and incinerators or when biomass burns in forest fires. Polycyclic aromatic hydrocarbons are discussed as possible starting materials for abiotic syntheses of materials required by the earliest forms of life. Nomenclature and structure The terms polyaromatic hydrocarbon or polynuclear aromatic hydrocarbon are also used for this concept. By definition, polycyclic aromatic hydrocarbons have multiple rings, precluding benzene from being considered a PAH. Some sources, such as the US EPA and CDC, consider naphthalene to be the simplest PAH. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Priorities List
The National Priorities List (NPL) is the priority list of hazardous waste sites in the United States eligible for long-term remedial investigation and remedial action (cleanup) financed under the federal Superfund program. Environmental Protection Agency (EPA) regulations outline a formal process for assessing hazardous waste sites and placing them on the NPL. The NPL is intended primarily to guide EPA in determining which sites are so contaminated as to warrant further investigation and significant cleanup. As of 2022, 1333 sites are on the list, and 43 sites have been proposed for listing. 448 sites have been deleted from the list. Process for listing The Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA), also known as "Superfund", requires that the criteria provided by the Hazard Ranking System (HRS) be used to make a list of national priorities of the known releases or threatened releases of hazardous substances, pollutants, or contamin ...

Lakes Of Worcester County, Massachusetts
A lake is an area filled with water, localized in a Depression (geology), basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the World Ocean, ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glacier, glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic dra ...
